越来越多的终末期慢性肾病患者不仅需要新的治疗方法,而且需要使用令人信服的临床前疾病模型和创新的分析技术进行开创性研究。本研究的目的是介绍一种使用微型计算机断层扫描(µCT)的整个小鼠肾脏的虚拟组织学方法,以缩小单层平面组织学与3D高分辨率数据集之间的差距。一种基于磷钨酸扩散的体外染色方案被用来增强肾脏软组织的X射线衰减。随后的CT扫描可以(I)更详细地检测肾皮质、髓质和骨盆,(Ii)形态变化的分析,(Iii)这些部分的体积和放射不透明的量化,以及(Iv)基于单侧输尿管梗阻模型的放射不透明改变的肾脏纤维化重塑的量化。因此,基于PTA增强CT的虚拟组织学未来将有助于完善肾脏相关小鼠疾病模型的临床前研究结果。
The increasing number of patients with end stage chronic kidney disease not only calls for novel therapeutics but also for pioneering research using convincing preclinical disease models and innovative analytical techniques. The aim of this study was to introduce a virtual histology approach using micro computed tomography (µCT) for the entire murine kidney in order to close the gap between single slice planar histology and a 3D high resolution dataset. An ex vivo staining protocol based on phosphotungstic acid diffusion was adapted to enhance renal soft tissue x-ray attenuation. Subsequent CT scans allowed (i) the detection of the renal cortex, medulla and pelvis in greater detail, (ii) the analysis of morphological alterations, (iii) the quantification of the volume as well as the radio-opacity of these portions and (iv) the quantification of renal fibrotic remodeling based on altered radio-opacity using the unilateral ureteral obstruction model. Thus, virtual histology based on PTA contrast enhanced CT will in future help to refine the outcome of preclinical research on kidney associated murine disease models.
